Population Ecology -
Chase and I reviewed the vocabulary associated with population ecology and then discussed what would happen to a population under different conditions and situations. Chase wrote out a list of density dependent limiting factors that control the carrying capacity of a population, as we discussed how a community provides the resources for every population, but only to a specific degree. Chase then graphed out the population of fruit flied grown in a controlled environment and given a set amount of food every day, and also a rabbit population, living in un-restricted space and having un-limited amounts of food. She compared and contrasted the two graphs and identified the one showing a logistical growth pattern and the one growing at an exponential rate. We then reviewed how population growth is calculated, discussed why engineers would want to know the predicted growth of a community before building roads and /or bridges. We figured out the population per capita of several countries, and identified which was better set to handle density in-dependent limiting factors such as famine and drought. Homework: study all vocabulary and population ecology concepts (chapter 6 and 7) for test on Thursday.
